[T]he treats that Wakefield first made at the inn, which she and her husband, Kenneth, owned, were so tiny, that a single cookie — the size of a quarter — was not quite a bite…. the tinier versions turn out quite crunchy…

Now, is this the invention of the chocolate chip cookie, or the invention of the chocolate chip cookie recipe? I remember reading that recipes themselves were a rather modern invention because “standard” weights and measures weren’t around.

And yes, if was harder to standardize weights and measures back in the day, but that is part of why professional bakeries use ratios (aka baker’s percentages). You can scale a recipe to any measurement that way. It wasn’t perfect- no standardized yeasts and such but it was doable.
